Exposures to rubber cements and solvents were investigated on December 2, 1980 and June 24 and 25, 1981 at Uniroyal, Incorporated (SIC-3069), Mishawaka, Indiana. Evaluation was requested by a representative of the United Rubber Workers International Union for 60 Fuel Cell Assembly Area workers, following reports of dermatologic problems. Work processes were observed; personal and area air samples were analyzed. Medical interviews were conducted with 20 workers. Exposures to methyl-ethyl-ketone (78933), toluene (108883), and acetone (67641) were below the respective criteria (source unspecified) of 590, 375, and 1780 milligrams per cubic meter (mg/m3). Exposures to hexane (110543) and acetone (111659) were also below the short term limit of 1800mg/m3. Ventilation was adequate. Workers reported various skin disorders, in spite of the use of protective creams and cleaning solutions. Glove usage was rare, as workers felt gloves hindered work. The authors conclude that affected workers are exposed to a variety of potential irritants, and that a health hazard exists. Some may become sensitized to one or more of the agents. The authors recommend use of protective gloves and creams, improved hygiene, and medical monitoring.
